Yes stock battery and syncing all turned on, wifi on all the time as well.
The only thing turned off is gps, I turn it on when using maps and off otherwise
I also have been using the phone quite a bit, playing some games, downloading from the market and using the internet using wifi

However I prefer to be safe than sorry, Apps DO get into the genuine market with virus's in them and although they do get removed and remotely deleted while they are undetected they can do whatever they like

I use Lookout security, its free and as well as being a very good antivirus, it also has the facility to tell you where your phone is (and more) should it be stolen

It also has a brilliant feature where if you lose your phone somewhere but your sure its nearby you can log onto the website and make your phone emit a siren sound that is very loud and easy to find where its hiding (usually down the side of a sofa in my partners case)

Well worth looking at, especially as they are the company who discovered the last virus in apps and notified Google who then deleted the apps from the market
